SPECIFICATION forming part of Letters Patent No. 232,795, dated September. 28, 1880.

Application filed June 11, 1850. (No model.)

To all whom it may concern:

Be it known that we, THoMAs A. WILLsoN and GEORGE \V. MEIGS, citizens of the United States, residing in Reading, Pennsylvania,

have invented certain lmprot'ements in Spectacles, of which the following is a specification.

The main object of our invention is to form the pivot or pivot-eye on a spectacle-temple with or without stop-shoulders in a simpler and more economical manner than that heretofore practiced, a further object being to prevent the accidental detaching of the pivot-pins of the temples from the end pieces of the spectacles. These objects we attain in the manner which we will now proceed to describe, reference being had to the accompanying drawings, in which- Figures 1, 2, and 3 are perspective views,

showing the manner of forming an eye on the temple according to our invention; Figs. et, 5,

' and 6, perspective views, showing our method of forming an eye and stop-shoulders 011 the temple; Figs. 7, S, 9, and 10, plan views of Figs. 2, 3, 5, and 6, respectively; Figs. 11 to 17, inclusive, perspective views, illustrating modifications of our invention; and Fig. 18, a sectional view of an end piece having a pivot pin secured thereto in accordance with our invention.

Figs. 1 to 17 inclusive, are drawn to a greatly exaggerated scale, Fig. 18 being on a somewhat smaller scale.

The invention relates to that class of tom- 5 ples which consist of thin steel wire and are used in connection with the finer and lighter classes of spectacles.

Usually the eyes and stop-shoulders of such temples are formed by forginga block of steel to the desired shape directly on the end of the temple-wire, or by forging such block separately and securing it to the temple-wire by soldering or brazing.

The operations of forging, boring, finishing,

5 and attaching the eye-block are timeconsuming and expensive, and the eye when completed is not as light as is desirable.

In carrying out our invention we discard the usual plan of forming on or attaching a forged block to the temple-wire, and form the pivot or pivot-eye with or without stop-shoulders from wire in the following manner:

In forming a simple eye on the temple, as shown in Figs. 1, 2, 3, 7, and 8, the templewire a, previous to tempering, is bent at the proper distance from the end, the bent portion being laid back straight along the wire a for the required distance, and the free end then wrapped around the wire to, thereby forming on the latter a tongue, I), of doubled or folded wire, terminating in the coil d. See Fig. 1.) The tongue bis then bent round in order to form the eye f, which may be either elastic or inelastic, the end of the tongue b being secured by soldering or brazing, as shown in Figs. 2 and 7, if an inelastic eye is desired, but if it is desired to produce an elastic eye, the end of the tongue is allowed to remain unconfined, as shown in Figs. 3 and 8, so that after the I wire is tempered the eye will embrace the pivot-pin with an elastic pressure.

The doubled wire forming the tongue I) may be united by soldering, and the coil (1 may also be soldered to the wire a to insure solidity.

It is preferable in making an elastic eye, however, to allow the double wire forming the tongue I) to remain disconnected, so that the eye is free to expand against the top and bottom plates of the end piece, as well as to I, closely embrace the pivot-pin.

The coil (2 may be finished by filing, hammering, or otherwise, so as to present the appearance of a solid collar on the wire at, al-

though in most cases this will not be necessary. 8 5

In making the temple with stop-shoulders, as shown in Figs. 4, 5, 6, 9, and 10, the wire a is bent so as to form at the base of the tongue I) projections m m at right angles to said tongue, these projections, when the tongue is bent to form the eye f, occupying the proper relation to the said eye.

The eye f, being formed of doubled wire, possesses the requisite strength and rigidity, and the same is true of the stop-shoulders m 5 m, the strength of the eye portion of the temple being further increased by the coil (1. The latter, however, although preferable for this reason, is not absolutely essential, for in some cases the temple may be constructed as shown IQQ in Fig.11, in which theendofthe wireis merely doubled or folded on itself to form the tongue I), or as shown in Fig. 12, in which the wire is folded so as to form the tongue I) and projections m, the coil at being dispensed with.

The temple, instead of being made of a single wire, a, as shown and described, may be doubled and twisted, as shown in Fig. 13, where additional strength is desired.

In some cheap classes of spectacles it is usual to form on the temple, in place of an eye adapted to a pivot-pin, projections adapted to openings in the end piece and serving as pivots for the temple.

In making a temple of this class we may adopt the construction shown in Figs. 14 and 15, the double wire tongue b in this case having its limbs bent so as to form the vertical pivotingprojections. The same plan may also be adopted in connection with temples unprovided with the coil 61 and stop-shoulders m.

Our improved method of constructing the pivot or pivot-eye and stop-shoulders of the temple is simpler and more economical than the usual plan referred to at the beginning of the specification, the spectacles, moreover, presenting a lighter and neater appearance than usual, without any impairment ofthe strength of the joint.

When the pivot-pin m of the temple is simply screwed into the end piece, 3 of the spectacles, as usual, the movement of the elastic eye on said pin frequently causes the latter to work loosean objection which we overcome by soldering or brazing the pivot-pin w to the end piece, as shown in Fig. 18, the said pivotpin being thus permanently secured to the end piece, and hence free from the above ob- 4o jection.

rate piece of wire, as shown in Fig. 17. This method of construction, however, is not as convenient as that before described by us and illustrated in the other views of the drawing.

We claim as our invention- 1. The mode herein described of forming the pivot or pivot-eye on a wire temple, said mode consisting in forming on the end of the temple-wire a double wire tongue, b, provided with pivoting-projections or bent so as to form an eye, all substantially as specified.

2. The mode herein described of forming a pivot or pivot-eye and stop-projections on a wire temple, said mode consisting in forming on the end of the temple-wire a double wire tongue, b, and projections m m at right angles thereto, said tongue I) having pivoting-projections, or being bentso as to form an eye, all substantially as set forth.

3. The mode herein described of forming and strengthening the pivot end of a wire temple, said mode consisting in forming on the end of the temple-wire'a coil, d, and a double wire tongue, I), with or without projections m, the tongue having pivoting-projections, or being bent so as to form an eye, all substantially as specified.

4. As a new article of manufacture, a wire temple having a pivoting portion composed of wire doubled and bent, all substantially as specified.

5. As a new article of manufacture, a wire temple having a pivoting portion and stopprojections m m adjacent thereto, said pivoting portion and stop-projections being composed of wire doubled and bent, all substantially as set forth.

6. As a new article of manufacture, a wire temple having a coil, (1, and a double wire tongue, forming a pivot or pivot-eye for the temple, with or without stop-projections m, as specified.

In testimony whereof we have signed our names to this specification in the presence of two subscribing witnesses.
